SPECIFICATION forming part of Letters Patent No. 611,202, dated September 20, 1898.

Application filed April Z, 1898. Serial No. 676,240. (No model.)

Tg) all whom it may concern:

Be it known that I, CHARLES M. HoRToN, a citizen of the United States, residing at Superior, in the county of Douglas, State of Visconsin, have invented certain neT and useful Improvements in Combination Structural Metal Beams, Gil-ders, and Posts; and I hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to combination structural metal beams, girders, posts, or struts; and it consists in applying to the flanges of an I-beam channel plates or pieces with or without flanges, said channel plates or pieces being provided with channel walls or ribs adapted to be rolled upon the flanges of the I-beams while in a heated condition for binding the parts together without the use of rivets or bolts.

It also consists in certain other novel constructions, combinations, and arrangements of parts, as will be hereinafter more fully described and claimed.

In the accompanying drawings, Figure 1 represents a cross-sectional view of a beam, girder, or post constructed in accordance with my invention. Fig. 2 shows a similar view with the channel-plates turned. inthe opposite direction. Fig. 3 representsatransverse section through a beam having channel-plates applied thereto, the said channelplates having flanges upon each side; and Fig. 4 represents a beam having plates applied to it, said plates having no edge anges.

The object of my invention is to provide structural metal beams or posts of various desirable sizes and shapes without resorting to the use of rivets or other weakening means, therebydepriving the metal of its full unpunotured strength.

A in the drawings represents an integral I-beam, and B channel plates or beams.

The I-beam A may be constructed in any well-knownor usual manner, buty is preferably provided witli flanges having their inner edges rounded. In building up a structural beam I contemplate applying channel plates or beams, as B, upon the edges of the I-beam, and in order tosecure the said channel-plates firmly in place upon the edges of the said I-beam flanges or channel-walls, as b b, are formed upon the web of the channelplate. These channel-walls b maybe formed upon the opposite sidevfrom the flanges of the channel-iron, as shown in Fig. 1 of the drawings, and are adapted to inclose the flanges of the I-beam between them. When the structure is being assembled, the parts are preferably in a heated condition and the assembled structure is passed through suitable rolls and the walls b h are rolled over and turned down upon the iian ges of the I-beam A.

As shown in Fig. 2 of the drawings, the channel walls or ribs c may be applied between the flanges c of vthe channel plates or beams C. These are also rolled down upon the flanges of the beam A in applying the parts together. As it appears in Fig. 3 of the drawings, the channel walls or ribs d may be applied to the webs of double channel plates or beams, as D, the said plates or beams D being thus practically I beams. The flanges d are rolled down upon the iianges of the I-beam A, as heretofore described. It

will be evident that the plates or beams ap-v plied 'to the I-beam A may have no edge iian'ges at all, as shown at E in Fig. 4 of the drawings. In this instance the beams E are provided With channel walls or ribs, as e e, which receive the flanges of the I-beam A and are adapted to be rolled' down thereon for holding the parts together. As above mentioned, the parts are preferably applied together and rolled when either the beam or the channel plates or beams, or both, are in a heated condition, so that when the flanges of one are rolled down in suitable rolls upon the flanges of the other they will take a firm hold thereon and be held rigidly together without the necessity of using rivets or other puncturing means. The rolling and forming of the component parts and the assembling and rolling of the combined structure are preferably done in a substantially continuous operation to avoid the necessity of reheating.

I do not Wish to beunderstood as limiting myself to any particular degree of curvature in the edges of the flanges or the walls of the channels.

It will be apparent that variations and modifications in the forms of the plates and beams shown and described may be made IOO Without departing from the spirit ofvmy ining the parts rigidly together, substantially Io Vention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

A structural beam or post, comprising an integral I-bhearn and one or more Channel plates or beams having channel-Walls for ieeeiving the flanges of the I-beam and securas described.

In testimony whereof I hereunto afx my signature in presence of two Witnesses.

CHARLES M. IIORTON.
